ThevSchedule referred to in these Letters Patent: aind making part ofthe same.

I, GEORGE P.1`ULLER, of H umphrcy, iii the county .of Cattarangus andState of New. York, have invented prevent any ame which maybe broughtthere by any cause passiiigiuto the tube. When the lainp'is to beextinguished the slide is turned to cover the openings, to prevent theesca-pc of gas.

To enable others skilled in the art to which niy iinprovementuppcrtaiiisto make and use niy invention, 1 will now give a detaileddescription thereof'.

In the accompanying drawing which makes a part ot` this specification-Figure 1 is a vertical section of a iaiiip provided with the improvedburner.

Figure 2- is a side elevation of the safety-tube C.

Figure 3 is a. likegview of the said tube C and slide E, in connectiontherewith.

Like letters 'ni all the figures indicate the saine pai-ts.

A is the oil-chamber.

B is the wick-tube, to which is connecte-.l the detachable safety-tube Cand the burner l), or any ordinary burner.

The safety-tube C has iii its uppcr end a series of openings, a, throughwhich air tlows and coniniiiiglcs with the gas as itpasscs up throughthe wick E to the burner, and also has a t'ree passage through theopenings b to the gas-chamber, to keep up an equiv libriuni hetwccii theair in the gas-chamber and the external air outside of the lamp.

The possibility 0f explosion is prevented by any ex,

The free circulation otair through the tubes,as de.- scrilied, preventsa communication ot' li`cat.i'roiii the burner to the hotly ofthe lanip.Q F is :i tubular slide which surrounds`the tube.

1t is pierced willi siiiall holes (l, which, when the lamp l'iiiriiiiig,are broughtiiitoconiniunicatioii with the pci't'orntioii'sot'tlie'satity-tuhc U, the holes ot'the slide heilig siiiall enough toprevent any thune bring carried into the tnhc and communicating with thegus.

\\'lieii the laiiip is to be extinguished the slide is turned partlyaround to close thc openings l ot' the safety-tube so as to prevent anyoutllow ot" gus.

'llic iiiovciiieiits ot' the slide. are. regulated hy the slot fin thelower edge :ind uthe pin y, which projects t'roiii the sideotl thetulic, as secu in tig. 3.

1t' deciiicd necessary, the slide nia) he provided willi a thiiuhlesurrounding it, constructed ot' thin wire gauze.

llie object of thc extension ot' the tube (l to near the hottonrot'tlieoil-cliaiiibcr A is to prevent the di? rcctfupward pressure ot'gas, aswithout this provision danger might occur it' through `neglect the slideF 'should be left closed. Yet, it' desired, the tube may be iliade onlylongr enough t'oi' the combination therewith ot' the slide F. Y 1

\Vliat`l claini as new, and desire to secure by Letters Patent, is v Thecombination ofthe slide I" with the safety-tubo C, the slide beingprovided with holes (I, and the tube with pertiil'atoiis (l,substantially iii the liiuiinir and for the purpose set forth. 2'
